About
Math Games Central is a free library of maths practice for children: 33 topics of it, as worksheets you can print and as levels you can play, with nothing to sign up for.
Why it exists
Most free maths worksheets online are a doorway to something else — an account, a mailing list, a subscription after the third page, or an advert placed beside a nine-year-old. The maths is the bait. This site is an attempt at the plain version: the practice, printable, free, and finished.
Every question is generated and then independently checked by a second piece of code that works the answer out a different way — the way a child would, counting and pairing off rather than subtracting. A worksheet with a wrong answer key is worse than no worksheet, because a child who did it right gets told they were wrong.
The rules it keeps
- No accounts, ever. Progress lives in your browser and moves between devices by a code you copy yourself. See privacy.
- Nothing loads from anywhere else. No fonts from Google, no scripts from a CDN, no embeds. A build that breaks this rule fails and does not ship.
- It has to print. A worksheet is the point, not a consolation prize for people without a tablet, and every sheet is designed on paper first.
- It has to work on a school Chromebook. Old machine, slow connection, shared screen, no installs.
- The word problems are fictional. Invented names, invented places, and phone numbers that begin 555, so nothing in a maths question points at a real person.
The Professor
The Professor is the capybara in the glasses. He turns up in the margins of worksheets to say the thing the instructions left out — why the denominator stays put, which mistake this page is really about, what to try when you are stuck.
He has no surname, and that is deliberate: he had one until a search turned up someone already teaching maths under that name, at which point keeping it would have been a small convenience bought at somebody else's expense.
Who makes it
One person, working on it a piece at a time. There is no company behind it, no investor expecting it to start charging, and no plan to sell your attention to anyone.
If something here is wrong — a bad answer key, a sheet that prints badly, a page that will not load on a school machine — that is worth hearing about, and worth fixing.
